我试图将我的自定义包从symfony 3迁移到symfony 6.2支持，但是被InvalidConfigurationException卡住了。
我一直在遵循this和this文档，但似乎遗漏了一个重要部分。

<?php

namespace Schoenef\HtmlToPdfBundle;

use Symfony\Component\HttpKernel\Bundle\AbstractBundle;

class SchoenefHtmlToPdfBundle extends AbstractBundle
{

}

//相关性注入/schoenefHtmlToPdfExtension.php：

        $config = $this->processConfiguration($configuration, $configs);

        $loader = new YamlFileLoader($container, new FileLocator(__DIR__ . '/../../config'));

    }

有人能看出这个可能非常明显的错误吗？我只得到：

Unrecognized options "provider, timeout, apikey, default_options" under "schoenef_html_to_pdf". Available options are "".

非常感谢！
